R11 @ 1k5 and R12 @ 330r results in a Vbe ratio of 5.545:1
With a Vbe of 700mVbe you end up with a bias voltage of 3.88V
That is too high. The output stage could run far too hot.
It depends on the Vbe of the multiplier and the drivers and the outputs.

With 200r trim pot added and set to maximum, the ratio drops to 3.83:1 giving a bias voltage of ~2.68V if Vbe=700mVbe
That is still too high for first start up.
